LAWN SPRINKLER.

Application 'file'd September T 0 all whom it may oonccwt:

Be it known that I, I GnenonGnisnNnonrnn, a citizen of ithe United States, and a resident-of Warrenton, in the county of Clatsop and State of Oregon, have invented a new and Improved Lawn Sprinkler of: which the following isa full, clear, and exact description.

Thisinvention has :relation to .a lawn or garden sprinkler and contemplates a simple and inexpensive sprinkler adapted to be connected with a garden hose for-effecting the distribution of the water a'tlierefrom. over a predetermined area.

One ofthe principal objects oflthe present invention is to provide a sprinkler which will more closely simulate the action of rain by projecting the spray from an elevation upon the shubbery, flowers, or other plants.

Another object resides in the provision of means operable by. the force of the water for rotating the outlet nozzle and means for regulating the speed of rotation without diminishing the flow of the water, said lat ter means being further operable to hold the nozzle in a stationary position when desired.

WVith the above recited and other objects in View, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.

In the drawings- Figure 1 is a side view of a sprinkler constructed in accordance with the invention, parts being shown in section.

Fig. 2 is a horizontal sectional view taken approximately on the line 22 of Fig. 1.

Fig.3 is an enlarged fragmentary perspective View illustrating the clamping means interposed between the stationary and rotary sections of the sprinkler.

Referring to the drawings by characters of reference, 10. designates a stationary pipe section which is provided adjacent its lower end with a fitting 11, having a laterally and downwardly projecting intake nozzle 12 to which the outlet end of a garden hose or 1, 1922. :Serial No. 555,760.

water conduit 13 is attached. The lower free openend of the fitting is closed by asupporting leg 14 which is threaded at its. upper end into the lower end of the fitting. The supporting leg 14 is pointed at its lower end as at 15 for facilitating the insertion andanchoring of the lower end of the leg in the ground whereby said leg constitutes means for holding t-hestationary pipe section 10 in a vertical ;or upright position. The sprinkler further includesa rotary pipe section having a sleeve 16 secured to the lower end and embracing the upperend of the stationary pipe section 10, said sleeve being connected to the rotary pipe section for turning movement therewith by means of a water-tight coupling, whereby said rotary section extends upwardly therefrom in axial alignment therewith. A packing gland 17 surrounds and embraces the lower end of the sleeve and the stationary pipe section at their juncture. The bore or inner periphery of the rotary section 16 is formed with a spiral rib 18 against which the water impinges during. its passage therethrough for effecting rotation of the section 16. The upper'end'of the section 16 has connected thereto an angular pipe section 19 which may be formed integral therewith if desired and to the outer end of said section or angularly disposed extremity a spray nozzle 20 of any approved type, is attached, whereby the water will be projected therefrom at an upward and outward angle. In order to provide means for regulating the speed of rotation of the rotary section 16 without diminishing the flow of the water, or for holding the rotary section stationary when desired, a clamping element is employed. The clamp element consists of a lower split ring 21 which is permanently clamped by a bolt 22 around the stationary section 10 immediately below the coupling or gland 17. The lower split ring 21 is connected by an offset arm 23 to an upper split ring 24 which encircles the rotary section 16 immediately above the coupling or gland 17. The upper split ring is brought into adjustable frictional embracing engagement with the rotary section 16 by means of a bolt 25 having a winged nut or thumb screw 26 threaded on one end. Under this arrangement, the frictional embracing engagement may be varied to admit of any t esired speed of retation between the maximum and a complete standstill without diminishing the flow of the water from its source of supply.

I claim:

1. A lawn sprinkler of the character described comprisin a tubular base section having a fluid in ct for attachment to a source of supply and means for removably attaching a supporting leg, a plurality of tubular sections supported by said base section, including a stationary section and a rotatable section swiveled thereon, a sleeve surrounding the j ointure of said stationary and rotatable sections, and a clamping element having a substantially U-shaped arm adapted to fit over said sleeve and adjustable clamping bands at each end of said arm for attachment to the stationary and rotatable sections respectively whereby the rotation of said rotatable section is controlled.

2. In a lawn sprinkler comprising a plurality of tubular sections, one of which is swiveled on an adjacent stationary section and adapted to be rotated by passage of fluid therethrough, means for controlling the rotation of said section consisting in a pair of connected clamping bands, one off which is adapted to adjustably engage the surface of the rotatable section and the other to engage the surface of an adjacent stationary section.

3. A lawn sprinkler of the character de scribed comprising a tubular base section having a fluid inlet for attachment to a source of supply, a supporting leg removably inserted in the open lower end of the base sect-ion for closing the same when associated therewith, a plurality of tubular sections supported by the base section and including a stationary section and a relatively rotatable section swivelled on the stationary section a packing sleeve surrounding the juncture of said stationary and rotatable sec tions and means for respectively locking the rotatable section to the stationary section or releasing the same therefrom comprising a pair of split clamping'rings respectively e1nbracing the rotatable section and stationary section and an offset connecting arm for said rings overlying the packing sleeve.
